[Elecraft] KAT500

So, I have not seen any documentation of the KAT500 and the only photo image I have see of the back of a KAT500 (on the Elecraft page is not that clear).

But,  you must be saying that there are TWO AUX adapters on the back of a KAT500.   Is that the case?

I am curious as to how the average Elecraft user gets to learn this information.  I have not found any KAT500 documentation that might describe these things.

Here, let me ask: is this "additional" cable needed to use the KAT500 with a KPA500 and K3 for all normal operating.  I already placed my order for the KAT500 and I am wondering if I ordered enough stuff.  I have the K3+P3+KPA500.

Been waiting patiently for that order to be filled so it would be nice to know if I have to order another cable before the KAT500 finally gets here.
